Editor's Notes
- #5 Let’s begin with what is internet of things. Right now it's really exciting to see the momentum behind the internet of things. When you take a traditional electronics and add computing, connectivity and add a layer of intelligence you end up transforming the experience. There are a whole range of possibilities you can imagine. The thing that is talked the most in the world of internet of things is Smart Home. Your thermostats, lights, music all working together to give you a better experience. But with internet of things, possibilities go way beyond that. Imagine a farmer who could monitor all his farmlands on his smartphones. 100s of sensors in his farmland collecting the data and using something like Azure IOT Hub, if we could add intelligence on top of it, we end up transforming the way he does agriculture. Today, there’s two major trends going on. Number one is the rapid rise in IOT And number two is the rapid rise in Artificial Intelligence and Machine learning. And in many ways these are intersecting with each other to create something really cool. Not only that, now is the era of machine learning and artificial intelligence. What if this farmer is able to leverage machine learning and artificial intelligence on the data we gathered and make sensible predictions like crop yield, rainfall and much more. And that’s the future of Internet of things. So I see as a range of possibilities, and I think its endless. The world we are living right now is The Age of Smart It started with the smartphone. Now everyday devices like thermostats,lights,cars, TVs etc are being made smart by connecting them together over networks and to the Internet. These devices will not only be able to send data to the Internet but they will also be controlled over the Internet. These devices will become “things” on the “Internet of things”. The Internet of Things (IoT) presents exciting opportunities for developers and businesses, enabling everything from predictive maintenance to smart cities to connected factories.
- #6 This internet of things or IOT is influencing our lifestyle. IoT is creating a giant network where all the devices are connected to each other and providing them with the capability to interact with each other. This is driving the automation to a next level where devices will communicate with each other and make decisions on their own without any human interventions.
- #7 According to Statista research it is expected to be 30 billion connected IOT devices by the end of this year. And that's a lot of devices. And today we will see what are these 30 billion devices that are connected over the internet. Connected sensors, devices, and intelligent operations can transform businesses and enable new growth opportunities and with Microsoft Azure Internet of Things (IoT) services its so much easier, reliable and faster.
- #9 The internet of things can be defined as the interconnection of the every day through the use of the internet By being connected to the internet these “things” can communicate with each other by sending and receiving data. Some common examples of an IoT device would be: Amazon Echos, Fitbit watches, Your fitness trackers, thermostats, door locks, and pet feeders. And what not! These devices can send and receive information from other devices and make our lives a bit easier. By having a smart lock you wouldn’t need to carry your keys around anymore because you can unlock the door with your phone! Wearing a smartwatch is a great idea if you wanted to keep your health upto the mark. The Thermostat can connect to the internet and you can even control it with your phone. By using this connection you could set your preferred temperature for your home while you are leaving work and by the time you get home it would be exactly to your liking.
- #10 IoT applications can be described as Things (or devices), sending data or events that are used to generate Insights, which are used to generate Actions to help improve a business or process. An example is an engine (a thing), sending pressure and temperature data that is used to evaluate whether the engine is performing as expected (an insight), which is used to proactively prioritize the maintenance schedule for the engine (an action). Typical IoT solutions have three key elements in common—things, insights, and actions. Let’s look at each one. Things: The devices or sensors you want to connect to the cloud. These can be intelligent edge devices with processors capable of running processes and functions or low-power devices that simply collect information. This element encompasses the full device lifecycle, including device security, monitoring, and management. Example: a sensor sends data about the status of a water pump. Insights: The useful aspects of the data captured by the IoT devices, made possible by data processing and analytics capabilities. This can include “hot path” data that is analyzed in real time, and “cold path” data that is stored for batch processing later. Example: the data is analyzed using machine learning to determine when maintenance is needed. Actions: What you ultimately do with the data, whether presenting it through a visualization tool, alerting a human to do something, connecting to a business process, or sending a message back to the device. Example: a field service technician receives an alert when maintenance is required, and a work order is automatically generated.
- #13 Azure is a cloud computing service by Microsoft which is widely used for building, testing, deploying and managing applications and services through a global network of data centers that are managed by Microsoft.
- #14 Azure IoT hub is a cloud service that enables bidirectional communication between devices. This service can be used for connecting various systems to the cloud and provides means of control and measurement of the systems. It can be used in various systems like home automation systems, greenhouse monitor and control systems, etc. For example, we can monitor the status of lights and fans in our homes from a remote place. We can also monitor if the house is vacant or not using data from some sensor like a PIR sensor. Based on this data from PIR sensor, we can control the lights and fans by sending data to the system remotely. Azure IoT Hub is a fully managed service that enables reliable and secure bidirectional communications between millions of IoT devices and a solution back end. Azure IoT Hub: Provides multiple device-to-cloud and cloud-to-device communication options. These options include one-way messaging, file transfer, and request-reply methods. Provides built-in declarative message routing to other Azure services. Provides a queryable store for device metadata and synchronized state information. Enables secure communications and access control using per-device security keys or X.509 certificates. Provides extensive monitoring for device connectivity and device identity management events. Includes device libraries for the most popular languages and platforms.
- #16 Connecting IoT devices with appropriate levels of security and reliability can be challenging. At the same time, security and manageability of IoT devices can be even more critical than typical enterprise devices because they control business- and safety-critical machines and processes.
- #17 Temp sensor in fish tank was compromised was able to pull out all the information about Casinos If you are doing IOT, you must think about security. IoT devices are often accessible in the field, they require a secure authentication mechanism to guarantee data integrity and prevent security breaches. Azure IoT services are built with these situations in mind to enable rapid and reliable security across many scenarios. Devices can be secured using security tokens or X.509 certificates and private keys, so you have the flexibility to choose the method that works best for your needs and device portfolio. The Internet connection between the IoT device and IoT Hub is secured using the Transport Layer Security (TLS) standard. Azure IoT supports multiple TLS versions, and Azure IoT Hub allows definition of policies for each security key to control access to service-side APIs.
- #18 Most data becomes useless just seconds after it is generated, so having the lowest latency possible between the data and the decision is critical. IoT Edge optimises for performance between edge and cloud while ensuring management, security, and scale. For scenarios such as these, you can use Azure IoT Edge. Azure IoT Edge builds on IoT Hub, enabling you to move parts of your workload to the edge, reducing time spent by devices sending messages to the cloud and enabling faster reactions to status changes. Azure IoT Edge is made up of three components: IoT Edge modules are containers that run Azure services, third-party services, or your own code. They are deployed to IoT Edge devices and execute locally on those devices. The IoT Edge runtime runs on each IoT Edge device and manages the modules deployed to each device. Azure IoT Hub exposes specific interfaces to remotely monitor and manage IoT Edge devices, available through the Azure portal, the Azure CLI, or the SDKs.
